Depend what you mean by "water jet" do you mean the kind you would install inside a sub to squirt water out at people (not a really nice thing to do!)? Or the kind used as a propulsion system? Bilge pumps and other types of pumps can be installed on a sub to give it propulsion.

thx for reply m8
not the water pistol type even though that would be fun!!!propulsion to power a sub along and steering the thing as well..
cheers

In either case of the previous suggestions, I have reservations that they will be powerful enough as the main source of propulsion for a boat or submarine.
While the Graupner bow thruster is a bit overpowered as a thruster. I don't believe the propellers were designed for high powered thrust.

Actual jet pumps may be adaptable to your application by extending the shaft connection into a WTC. Since the submarine is below the water surface, jet pumps should not have any trouble with water intake.
